Dubai, UAE: The UAE Federal Tax Authority (FTA) has issued new guidance on the Multinational Enterprise Top-Up Tax, giving affected multinational groups more clarity on registration, entity classification and reporting requirements. The FTA published TTGREG1: Scope and Registration and TTGEIE1: Excluded Entities and Investment Entities on 26 August 2026. The Ministry of Finance has also issued Ministerial Decision No. 133 of 2026, which sets out requirements for the Pillar Two Information Return.
The latest guidance gives businesses more practical direction as they prepare for the UAE’s Domestic Minimum Top-Up Tax under the OECD Pillar Two framework.
Which Businesses Are Affected?
The rules do not apply to every business operating in the UAE. The UAE Domestic Minimum Top-Up Tax applies to UAE entities that are part of multinational enterprise groups meeting the global revenue test.
The group must have consolidated revenue of €750 million or more in at least two of the four financial years immediately before the relevant year. The DMTT applies for financial years starting on or after 1 January 2025.
This means multinational groups need to assess their global group revenue and UAE structure before deciding whether the Top-Up Tax rules apply to them.
For affected businesses, business tax advisory can help with reviewing the UAE tax position alongside the wider requirements of the new rules.
30 November 2026 Registration Deadline
One of the most important current dates is 30 November 2026.
For in-scope entities whose relevant fiscal year ended before 30 April 2026, the transitional DMTT registration deadline is 30 November 2026. The general registration rule is linked to the end of the first in-scope financial year.
Businesses that fall within the rules should therefore confirm their registration position and avoid leaving the assessment until the deadline is close.
Failing to meet a required registration obligation can create an administrative compliance issue. The new FTA guidance gives affected groups a clearer basis for checking their obligations and preparing their EmaraTax registration.
Exempt Person Does Not Always Mean Excluded Entity
The new guidance also highlights an important distinction for multinational groups.
Being an Exempt Person under UAE Corporate Tax does not automatically mean that an entity is an Excluded Entity under the Pillar Two rules. The relevant entity must assess its own position under the Globe rules.
This distinction is important for groups with entities that benefit from specific UAE Corporate Tax exemptions. Assuming that an existing exemption automatically removes an entity from the Top-Up Tax framework could lead to an incorrect compliance assessment.
Businesses should carry out a proper review of their structure, tax position, and reporting obligations. Tax and compliance planning can help businesses identify areas that require further review before registration and reporting deadlines.
New Pillar Two Information Return Rules
Ministerial Decision No. 133 of 2026 also provides a framework for the Pillar Two Information Return (PIR).
The decision covers filing requirements for UAE Constituent Entities, Joint Ventures and JV Subsidiaries. A group may also use a Designated Local Entity for the relevant UAE filing arrangements.
This means affected groups need to look beyond registration. They should also understand which entity is responsible for the required information reporting and how their UAE entities fit into the filing structure.
What Should Businesses Do Now?
Multinational groups with a UAE presence should first check whether they meet the €750 million global revenue threshold. They should then identify their UAE constituent entities, review whether any exclusion applies, and confirm their registration and PIR obligations.
Businesses should also keep their financial and tax information organized so that the required assessments and filings can be completed accurately.
For groups dealing with complex structures, auditing and assurance can provide an important review of financial information and reporting processes that support wider tax compliance work.
Why Professional Support Matters
The new FTA guidance gives multinational businesses more clarity, but applying the rules still requires careful assessment of each group’s facts and structure.
Dubai Business and Tax Advisors (DBTA) can assist businesses with tax advisory services, helping multinational groups understand their UAE tax responsibilities, review relevant requirements and prepare for important compliance deadlines.
The latest FTA guidance is a clear reminder that Pillar Two compliance is not only about calculating Top-Up Tax. Businesses must also understand their registration, classification, and reporting responsibilities before the relevant deadlines arrive.
